California High Speed Rail Authority – Construction Package 2-3

CAHSR

The Hanna Group was selected by the California High Speed Rail Authority for the Independent Site Engineer (ISE) Services as part of the Construction Package 2-3 (CP 2-3) Project and Construction Management Team.http://hannagrp.com/website/wp-admin/upload.php

The California High Speed Rail Construction Package 2-3 is a continuation of the Construction Package 1 project that extends the high speed rail (HSR) system by approximately 65 miles from Fresno, CA south towards Bakersfield, CA. The HSR corridor crosses various existing infrastructure including State Road 43, State Road 198, the BNSF, the UPRR, San Joaquin Valley Railroad, numerous local roads, and several waterways. All crossings along the corridor will be grade separated.

The major elements of this project include:

  • Approximately 12 million cubic yards of embankment for 65 miles of HSR track
  • 18 high speed rail bridges where the HSR goes over local city, county and state roads
  • 31 roadway bridges where HSR goes under the bridges as part of grade separation
  • Approximately 7 million cubic yards of roadway embankment

This project is a significant win for THG because we are establishing a relationship with a new client.

Santa Clara Valley Water District – Main Madrone Pipeline Restoration Project

SCVWD
The Hanna Group was selected by the Santa Clara Valley Water District to provide Construction Management Services for the Main Madrone Pipeline Restoration Project!

This project is located in Morgan Hill and will include the installation of almost 14,000 linear feet of 30” and 36” Pressurized Steel Pipe which replaces the existing water lines of various smaller sizes which over the years have been plagued with root intrusion and leakages. This project will restore the Main Avenue and Madrone pipelines to full operating capacity of 37 cubic feet per second from Anderson Reservoir. The upgrade includes replacement of a 1-mile section of pipe on the Main Avenue line which has been out of service since 1994, and restoration of approximately 1.25 miles of Madrone pipeline which has restricted capacity due to root intrusion and deterioration. The project is separated into three different segments all to be installed using typical open-cut construction methods. The segments break down as follows:

Segment 1 – 2,800 LF of 36” Pressurized Steel Pipe from Anderson Reservoir Outlet to Cochrane/Half Road
Segment 2 – 4,860 LF of 30” Pressurized Steel Pipe from Cochrane/Half Road to Main Avenue Ponds
Segment 3 – 6,300 LF of 30” Pressurized Steel Pipe from Cochrane/Half Road to Madrone Channel

The benefits of this project include:

  • Increases groundwater recharge by about 2,000 acre-feet per year in South County’s Llagas Groundwater Sub-basin, a sufficient water supply for 4,000 families of five.
  • Maximizes the delivery of imported water to treatment plants supplying drinking water to North County.
  • Saves energy, reduces operating costs, and cuts CO2 emissions by reducing dependence on Coyote Pumping Plant.

City of Folsom – Orangevale Avenue Bridge Rehabilitation

SCVWD
The Hanna Group was selected by the City of Folsom to provide Construction Management Services for the Orangevale Avenue Bridge Rehabilitation Project!

The Orangevale Avenue Bridge, constructed in 1915, crosses Gold Creek between Placer Mine Road and American River Parkway in the City of Folsom. In 1927 the bridge became a part of the Lincoln Highway, which at the time provided the best and fastest route between New York and San Francisco. From 1915 to 1948 the bridge provided the main connection between Folsom and Orangevale. During this time the bridge connected the citrus groves, orchards and produce gardens of Orangevale, Fair Oaks and Carmichael with the processing and shipping businesses in Folsom.

The open spandrel arch bridge is approximately 160 feet long and 20 feet wide with a 6” deck. Based on the age of the structure and a condition assessment prepared in 2007, it has been determined that removal and reconstruction of the eastern abutment and wingwalls along with the deck, beams, and spandrel columns are needed. The goal is to extend the bridge’s useful life and bring the load carrying capacity of the structure up to current standards, while protecting the historic appearance.

The major elements of this project include:

  • Temporary Sewer Relocation
  • Demolition of Deck and Spandrel Columns
  • Demolition of Abutment
  • Repair of Spalled Concrete on Arches and Remaining Abutment
  • Replacement of Columns, Deck and Abutment
  • Placement of Drainage Facilities
  • Placement of Permanent Sewer
  • Placement of Future Dry Utility Structure on Bridge

This project is a significant win for THG because we are establishing a relationship with a new client.
